Japan will be the first country to broadcast television content in ultra-definition. The information comes from the country’s Ministry of Communications, which scheduled the start of open network broadcasts for July 2014.
At first, the Japanese UHD will be transmitted via communication satellites, due to the large amount of data. The use of television satellites and ground antennas will follow, reducing costs.
The index reached by Japan, also called UHD or 4K, will have a resolution of 3,840 2,160 pixels. The value is four times higher than the current high definition, which reaches minimum rates of 1,920 x 1,080 pixels.
This standard used in Brazil in the transmission of digital signal, available since 2007. Unlike Japanese transmissions, however, the country still has about 50% of its population dependent on the analogue signal.
The end of analogue transmissions on Brazilian soil is scheduled for 2016. At this point, Japan will start testing 8K transmission, four times the UHD resolution. According to the country’s government, the 4K standard will already be available for the 2014 World Cup.
Costs and opportunities
In Europe, the cable TV network Eutelsat was the first to advertise high-resolution content. The French broadcaster has a channel dedicated to 4K, even with few users of the technology. A TV that supports these types of images can cost up to $ 38,000. In Brazil there are models for R $ 45 thousand.
Although they are expensive and the television sector is in crisis due to the popularization of other devices, the choice of Japan meets the demand of its market. Local companies like Sony, Sharp and Panasonic lead the ultra-definition TV sector and see the country as a major source of income.
